DRAWING-MOTION OF COTTON-COMBING MACHINES.

SPECIFICATION forming part of Letters Patent NO. 730,711, dated June 9,1903.

Application filed February 1, 1902. Serial No. 92,136. (No model.)

To (all whom it may concern:

Be it known that I, JAMES SLATER, foreman carder, a subjectof the Kingof Great Britain, residing at Oxford'Mills, Ashton-under-Lyne, in thecounty of 'Lancaster, England, have invented new and useful Improvementsin the Drawing-Motion of Ootton-Oombing Machines, of which the followingis a specification.

This invention relates to an improvement applicable to thedrawing-motion at the delivery end of cotton-combing machines; and

the objects of the said inventionare to diminish the draft and at thesame time toincrease considerably the productive capacity ton-combin gmachine to illustrate in what-relation to the carding-rolls thedrawing-rolls are placed.

A cotton-combing machine usually consists of a series of from six to tenheads AQB, and O, which are arranged along the side of a polished ironplate, along which the slivers proceed in parallel lines in thedirection of the arrows, Fig. 5, toward the drawing-rollers at thedelivery end of the combing-machines. Hitherto the drawing-rollers a.have been made in one continuous length, whereby the whole number ofslivers would pass through them into a single trumpet c,then through thecalendering or delivery rollers 19 into a single cant'. e., tenv sliversinto one can. According to my invention I divide the drawing-rollers ainto two sectionsand pass only, say, four or (see Fig. 5,) and eachsection of four or five ends passes through a separate trumpet c andthen through the calendering or delivery rollers 12, each four or fiveends into a separate can.

According to the old method the speed at which the combing-machinescould be worked and the slivers drawn and delivered into thecoiling-cans was limited by the maximum speed at which the coilers couldbe worked;

otherwise the draft was too great and the centrifugal force developedinterfered with the coiling action.

I have discovered that by dividing the delivery into two sections andpassing each section into a separate can running at the ordinary speedthe speed of the combing-machines could be very considerably increasedand the draft diminished,"thus almost doubling. the output withoutdeteriorating the quality of the product, or instead of using onedrawbox with the rollers divided into two sections, as illustrated, Imay employ two draw-boxes with ordinary rollers,' each provided with aseparate coiler, one placed at the delivery end of the combing-machineand the other at .or-near the center of the machine, and al- JAMESSLATER.
